Use the functions int86 or int86x.  With these, you load your registers
into a structure, then pass the registers to the function.  The function
takes care of the rest.  All registers can be set this way.

A C compiler that can't link to assembly is pretty poor.  MS-C can certainly
do it from version 4.0 on; I imagine it's been supported since version 1.0.
